Emerson Hyndman flashes a shot wide of the St Johnstone goal after Martyn Waghorn's initial effort is blocked by defender Steven Anderson.

Celtic's first attack of note ends with Kieran Tierney sweeping a curling effort over the crossbar from the left.

Liam Polworth steals possession from Nir Bitton and decides to have an ambitious shot from all of 45 yards. The ball skids wide, with Celtic keeper Craig Gordon diving across his goal just in case, or maybe just to stay warm on a bitterly cold evening.

At Tynecastle, a minute's silence for former Hearts striker Alex Young, who passed away this week aged 80. He was a title winner with the Jambos in 1958.

We are up and running...

Caretaker manager Graeme Murty talking to Rangers TV: " Clint (Hill) has been really good all season. He's a very, very good pro. He's a very good leader on the pitch. 

"Jason (Holt) brings a lot of energy and a lot of pace around the pitch.

"They know what's required today. They know it's about winning the game. It's about being efficient this evening and making sure we utilise our energies in the right areas and go and win the game.

"We've played them (St Johnstone) twice. We know they're going to be difficult to play against. It's about us trying to impose ourselves upon them.

"With the energy of the group, the mood of the group, I'm confident that we're going to go do that."

Tonight is the first time brothers Paul and Stephen McGinn have played a competitive match at senior level against each other.

Stephen McGinn is in his second spell at the Buddies after stints with various clubs down south - the midfielder and is now captain.

John McGinn left St Mirren for Hibs and is now a mainstay in their midfield, as well as breaking into the Scotland squad.

Let's be on the look-out for some tasty challenges!

Little surprise, perhaps, Dundee are unchanged for tonight's clash after thumping Motherwell 5-1 on Saturday.

Thistle only make one alteration to the side that beat Hearts, with Christie Elliott replacing Mustapha Dumbuya.

Two in-form teams meeting at Dens Park, and sides that have found their goalscoring form in recent weeks. A place in the top six is up for grabs, but also the sense that there is breathing space between the winners and the bottom two sides. Dundee's home form is impressive, but Partick Thistle are always organised and bright, and Kris Doolan is sharp in front of goal

Rangers are another team in need of a Premiership pick-me-up. The Ibrox side gained one measly point in February, suffering defeats to Hearts, Dundee and Inverness.

Aberdeen pulled away in the race for second but the Dons' defeat at Accies last night means Rangers can close the gap to six points with victory this evening.

Saints have lost three of their last four but can move within three points of the hosts with an away win.

Both of this season's previous meetings have ended 1-1, so it may well be another close encounter.

It looked like Hearts' fresh-faced gaffer Ian Cathro had turned a significant corner with back-to-back victories over Rangers and Motherwell but the Tynecastle natives are restless again after a home draw with Inverness followed by a chastening Scottish Cup exit at the hands of Hibs and a meek loss to Partick Thistle.

Now just one point ahead of St Johnstone, the Jambos are a distant 14 points adrift of second-placed Aberdeen, having been Celtic's nearest challengers in the week Robbie Neilson left.

It's been a grim year so far for Ross County, without a Premiership win in 2017. Manager Jim McIntyre is bidding to stem a damaging sequence of four defeats in five league outings which has the Staggies deep in the relegation mire.

Celtic make two changes as they target a 22nd consecutive Premiership victory in Inverness.  Mikael Lustig returns at right-back for Cristian Gamboa, who drops to the bench, while Gary Mackay-Steven comes in on the right flank for James Forrest, who still has some bruising from an injury sustained in the 2-0 win over Hamilton.

Inverness are forced to make two changes at the back, with Carl Tremarco injured, and Celtic loanee Jamie McCart unavailable against his parent club. The duo are replaced by Gary Warren and Brad McKay respectively.

Jake Mulraney is also injured, with Billy King coming into the starting line-up.

Here's what the Tynecastle pitch looked like seven days ago...

Inverness CT manager Richie Foran talking to BBC Sportsound:

"If we beat Celtic we are up to ninth, and I believe we can. I need my players to believe that as well. We have had two fantastic results the last couple of games, but I am a realist. We are going to need two or three Celtic players to have an off night, and I need all 11 of mine to be on it. 

"Belief is key in these kind of guys. The work-rate has to be there but you have to make things happen with the ball as well against the top teams."

Rangers make two changes from the side that lost to Inverness, as they look to recover from back-to-back Premiership defeats.

Clint Hill returns to central defence after recovering from a whiplash injury - the veteran replaces Danny Wilson.

In midfield, Jason Holt comes in for Andy Halliday. Both outgoing players are named among the substitutes.

St Johnstone duo Keith Watson and Danny Swanson are back in the line-up after overcoming injuries, while Liam Craig returns from suspension.

Watson replaces Tam Scobbie in defence, while attacking midfielders Swanson and Craig come in for David Wotherspoon and Chris Kane respectively.

The other Saints change sees Chris Millar drop out of central midfield, with Paul Paton his replacement.

Moussa Dembele scored a hat-trick when the teams last met in that 6-0 Scottish Cup demolition.

The Frenchman got two more in the weekend win over Hamilton, taking his tally to nine in four games and 29 for the season.

Goal number 30 can't be far away...

After a disappointing week for Hearts, boss Ian Cathro makes four changes to the side that lost at Partick Thistle.

Captain Don Cowie returns to midfield after recovering from a rib injury, with Faycal Rherras dropping to the bench.

Jamie Walker's head injury keeps him on the sidelines, with Sam Nicholson his replacement.

Striker Esmael Goncalves is suspended after being sent off at Firhill, so Bjorn Johnsen starts up front alongside Moha Choulay, who comes in for youngster Rory Currie.

Jay McEveley and Kenny Van der Weg come into the visitors' starting line up.

Hearts: Hamilton, Struna, Avlonitis, Nowak, Sowah, Tziolis, Cowie, Djoum, Nicholson, Choulay, Johnsen.

Substitutes: Noring, Rherras, Kitchen, Buaben, Martin, Bikey, Currie.

Ross County: Fox, Fraser, Naismith, Davies, McEveley, Van der Weg Woods, Chow, Curran, Schalk, Boyce, 

Substitutes: McCarey, O'Brien, Gardyne, Dow, Tumilty, Lalkovic, Dykes.

Inverness gave themselves a lift on Friday with a home win over Rangers, which nudged them off the bottom of the table.

However, Richie Foran's men find themselves back at the foot of the Premiership pile after Hamilton's success against Aberdeen last night.

The Highlanders are unbeaten in their past three league games but that run is broken by a Scottish Cup defeat - a hefty 6-0 loss at Celtic Park.

They also lost 3-0 on their November league visit to the champions.

Rangers:  Foderingham, Tavernier, Kiernan, Hill, Wallace; Holt, Toral, Hyndman; McKay, Miller, Waghorn. 

Substitutes:  Alnwick, Wilson, Hodson, Halliday, Forrester, O’Halloran, Garner.

St Johnstone:  Clark, Watson, Shaughessy, Anderson, Easton, Foster, Alston, Paton, Craig, Swanson, MacLean. 

Substitutes: Mannus, Scobbie, Wotherspoon, Smith, Coulson, Thomson, Cummins.
